[chimerax-users] chimerax label bug

[Lukas Kater]

Hi ChimeraX developers,

Sorry about that previous email...

Please let me know if there is a better way to report bugs.

I have been trying to use 2dlabel to annotate some things in a movie. I 
have stumbled across a number of problems:

1) creating 2 labels with the same name causes a crash (v1 quits and 
daily build just displays the log bellow under Fedora 32):
2dlab create ADP text "ADP state" color black size 26 bold true xpos 
0.03 ypos 0.92 visibility false
2dlab create ADP text "ADP state" color black size 26 bold true xpos 
0.03 ypos 0.92 visibility false

Traceback (most recent call last):

2) set bgColor hides labels
2dlab create ADP text "ADP state" color black size 26 bold true xpos 
0.03 ypos 0.92 visibility false
# label is there (although visibility false?!)
set bgColor white
#label is gone

3) labels created with visibility false are still displayed
see above. But I can change visibility with 2dlab change

Thanks for any help!
